'My invention relates to an improvement in a turning tool and itssupport for wood turning lathes, and the objects of my improvement areto provide a turning tool that cuts smoother, is attached to the lathemore securely, is more easily adjusted, lasts longer, and does work moresatisfactorily.

The character of the invention may best be understood by reference tothe description found in the following specification, when taken inconnection with the accompanying drawings in which- Fig. 1 is aperspective'view of my turning tool mounted on a wood-turning lathe, aportion only of the latter being shown;

Fig. 2 is a plan view of the tool; Fig. 3 is an end view of the same;Fig. 4 is a fragmentary perspective view of the tool, the cutting endonly being illustrated; 1

Fig. 5 is a perspective of the tool-"carrying block, the same beinginverted to show the bottom side; 7 V

Fig. 6 is a sectional elevation taken on omitted; V

Fig. 7 is a sectional plan view taken on broken line 77, Fig. 3; Fig. 8is a view-representing the position the cutting tool assumes, on andwith respect to the square, when turning the latter;

and a Fig. 9 is a perspective view of the revoluble nut operable withone of the adjusting screws for the tool-carrying block.

Similar reference characters are employed to identify like parts in allthe difi'erent views of the drawings.

Referring to Fig. 1 of the drawings, 1 represents a portion of the.wood-turning lathe to which the turning-tool is secured, 2 the powerbelt. 3' the headstock of the woodturning lathe, 4 the chuck threadedonto the arbor, which arbor is a part of the head stock, 5 the stick oflumber held in placeby the revolving chuck on one end and on the other,end by the ring 6; the other parts of the wood-turning lathe in Fig. 1,are not numbered, because they have no bearing in the description ofthis invention.

. This is done to hold the cutting-tool tighter.

' 12 is made to fit in the round hole 15 of the toolbase 14, anditspurpose is to secure the toolbase to the tool-carrying block, and toact as a pivot for adjustment of the block with respect torbase.

same time to bring correct adjustmentof the tool-carrying block forsetting the cuttingtool'in position-to do the work, and further to bringproper alignment between special collar 'screw 20' and revolublenut 11when adjustments are made of the toolrcarrying block.
